Write a C++ program (using switch case and nested if statement) that reads the following student information: ID prefix, ID Number, name, and GPA out of 4.0. Use 4 variables with appropriate (and different) data types for each piece of information (ID prefix, ID number, name, and GPA). The ID prefix is the letter at the start of the ID (e.g., if the student ID is u012345 then the ID prefix = 'u' and the ID number is 12345).

write a C++program that finds the total amount to be spent on a vacation. In Main ask the user for the number of days for the trip and the name of the person booking the trip. It should then call FindHotelCost() and pass both of these variables to that function. The FindHotelCost() function should give a message using the persons name who is booking the trip with the hotel bill. The bill will be 550 dollars for each day of the trip. It should then call AddRentalCar() and pass the name and number of days and the hotel bill to that function AddRentalCar() asks the user for the number of miles that were driven on the rental car and calculates the price of the car. It is $50 per day and .08 cents per mile driven. Show this charge to the user and then add it to the hotel bill for the total bill for the stay. Show this total to the user as well with the person’s name booking the trip.

Write a C++ program that will prompt for and read in the names (first and last) and the final exam scores (integer values in the range 0 to 250) for a class consisting of 50 students, calculate the average final exam score, and then display the average final exam score followed by a table consisting of 50 lines of data for this class - each line will consist of a student name, that student's final exam score, and the difference of that student's final exam score minus the class average final exam score. Requirements and Comments: • Your program must verify that a proper final exam score has been entered (an integer value in the range 0 to 250) and repeatedly request reentry for an invalid score, until a valid entry is made. • Do not assume that the user knows the value of the average in advance - your program needs to calculate the average. • Your program can ask the user to enter the scores only once. • Output from running your program should look like what is shown in the example…
